Prof Richard Ocaya from the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS) Qwaqwa  Campus has achieved a significant milestone with a newly patented invention. This patent, developed in collaboration with researchers from Turkey and Saudi Arabia, is the result of work that began in 2017, focusing on a special material known as graphitic carbon nitride.

This breakthrough in temperature measurement technology aligns perfectly with the university's Vision 130 commitment to innovation and addressing global challenges. The new device offers a unique solution to a longstanding issue in the field, providing accurate temperature measurements across an extremely wide range. Existing solutions often require multiple devices, leading to increased costs and reduced accuracy, but this invention simplifies the process.

The device, based on a combination of graphitic carbon nitride and silicon, can measure temperatures from -250°C to 250°C with exceptional consistency and linearity. This range and accuracy set it apart from current technologies, making it suitable for various applications, from standard temperature measurement to specialized settings involving extreme temperatures. It could be especially valuable in deep-space exploration, where equipment faces drastic temperature fluctuations.

The patent underscores the university's commitment to fostering collaborative research, a key aspect of Vision 130. Prof Ocaya attributes the success of the invention to the robust nature of the team, established in 2015. The team is now seeking to commercialize the technology by licensing it to a suitable partner, with organizations like NASA expected to show significant interest.

Prof Ocaya advises other academics considering patenting their inventions to ensure the patent solves a real problem uniquely and is based on sound principles. This makes the invention reproducible and protects it from being copied, assigning exclusive rights to the patent holder. Patenting allows for either manufacturing the devices or licensing them to third parties for royalties and profit. He notes that the main consideration is that the innovation must be practical and solve a specific problem in a novel and commercially viable way. He also acknowledges the challenge many academics face, as the "publish or perish" mentality often leads to choosing scientific articles over patents.

Despite securing the patent, Prof Ocaya and his team continue their research efforts, exploring new possibilities while balancing practical research with academic pursuits. He believes the invention will significantly impact the field of temperature measurement, being integrated into many new designs requiring such measurements.

The university proudly supports this innovative research and anticipates its real-world impact, furthering Vision 130's commitment to increasing UFS's research capacity and capability.

Art and science help us understand the world and our place in it

Although BioArt dates back as far as the 15th and 16th centuries with the work of Leonardo da Vinci, it is not every day that art and science combine. This rare phenomenon made its appearance when two totally different groups of students – studying arts and microbiology respectively – joined hands in an initiative to create BioArt.

This first-time undergraduate teaching collaboration between the Departments of Fine Arts and Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS), which is characterised by the use of living materials, such as enzymes, microbes and DNA, as well as scientific tools and methods, is exploring a number of questions. 

Different outcomes for arts and microbiology students

According to Prof Carlien Pohl-Albertyn from the Department of Microbiology, Biochemical and Food Biotechnology, one of the central questions explored in BioArt is the nature of ‘life’. “At which stage can matter be classified as being alive or living?” she asked. 

“We realised that the outcomes for the two groups of students would not be the same. For the microbiology students, the focus would be on the understanding and effective communication of a microbiological concept. For the art students the focus would be on the execution of the assignment using visual elements and applied theory of art,” said Prof Pohl-Albertyn.

Dr Janine Allen-Spies from the Department of Fine Arts added: “Art students will also be exploring strangely or previously unforeseen gaps between art and science that can be filled with imaginative interpretations which may forward creative insights in both BioArt as a developing art form and microbiology as investigative science.”

Students’ understanding of microbial evolution reflected in art
The art students had to visit the microbiology labs for their assignment as this is mostly a foreign environment for these students. “The paint medium they had to use was gouache. This medium with its bright colours works well to depict microscopic organisms in art,” Dr Allen-Spies said. 

On display at the Department of Microbial, Biochemical and Food Biotechnology on the Bloemfontein Campus, at a recent event to introduce this new initiative to a wider audience, was a range of visually and scientifically compelling paintings and artefacts (such as paintings, poems, songs, apps) which explore a theme within microbiology from a BioArt perspective that uses creativity to communicate concepts dealt with in the module Microbial Evolution and Diversity.

Any parties who are interested in buying the art can contact Dr Allen-Spies at allenj@ufs.ac.za.

Paintings and artefacts reflects students understanding of BioArt. At the recent opening of the BioArt exhibition at the UFS Department of Microbial, Biochemical and Food Biotechnology, was the work of Madeleen Jansen van Rensburg on display.

Pheny Mokawane, a Microbiology, Biochemical and Food Biotechnology student, wrote a poem for his BioArt project in the Microbial Evolution and Diversity assignment.
